Lane Recognizing Navigation Guide System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lane recognition route guidance system, and more particularly, to a lane recognition route guidance system for providing a driver with lane information on a driving vehicle by comparing lane information of a real road with lane information of a driving vehicle.

In general, the driver may drive while paying attention not to deviate from the center of the lane while the vehicle is driving, that is, to maintain the driving lane without leaving the lane.

As such, the reason why the driver keeps paying attention so that the vehicle does not deviate from the center of the lane while driving is to prevent traffic accidents that may occur during the lane departure.

However, the driver may cause a large accident because the driver does not recognize the departure of the lane due to driving in an abnormal road section or due to bad weather and drowsy driving.

To solve this problem, a vehicle is equipped with a Lane Departure Warning System (LDWS), and the lane departure warning system captures a front image by using a camera mounted on the front of the vehicle, and uses an image processing unit to drive a driving lane. The vehicle detects a warning and alerts the driver through a buzzer sound or voice guidance when the vehicle leaves the lane.

In addition, the Lane Keeping Assist / Support System (LKAS), which assists the driver's steering wheel operation to prevent departure from the driving lane when the vehicle is driving on the road, senses the driver's carelessness and assists in driving safely. In order to reduce the driver's steering burden and prevent large accidents caused by the departure of the driving lane in advance, torque is applied to the steering wheel by using the steering motor to return the vehicle to the center of the driving lane in a situation where the departure of the driving lane is expected to occur. And maintain.

Meanwhile, the conventional lane keeping support system performs steering control in a batch without considering the driver's steering tendency. That is, the steering control unit is designed to have the same steering control characteristics (maximum torque, response characteristics) under the same conditions regardless of the driver's steering tendency.

However, since the conventional route guidance system executes the vehicle's location information based on the GPS, it is not possible to detect and detect the position of the driving vehicle to the lane of the road. There was a difficulty, and there was a problem in that an expensive system such as a lane departure warning system or a lane keeping support system was applied.

The present invention relates to a lane recognition route guidance system for solving the above problems, and in particular, to provide lane information on a driving vehicle to a driver by comparing lane information of a driving vehicle with lane information of an actual road. It is done.

The present invention includes a recognition unit for recognizing a lane through a camera sensor mounted on a vehicle; A controller for recognizing a lane of a vehicle driving through the recognition unit and comparing the lane with a lane of an expected route; It is achieved by configuring an output unit for guiding information on the actual lane and the expected path lane of the running vehicle compared by the control unit.

As described above, the present invention compares lane information of a real road with lane information of a driving vehicle, and provides lane information on a driving vehicle, thereby minimizing the fear of lane change during driving at night, thereby increasing merchandise. At the same time, it is an invention that is effective in improving safety by allowing lanes to be changed in advance at complex intersections in the city.

Hereinafter, each component of the lane recognition route guidance system according to the present invention will be described with reference to the accompanying drawings.

As shown in (a) and (b) of FIG. 1, the recognition unit 100 recognizes a lane of a driving vehicle through a camera sensor mounted on the vehicle.

In this case, the recognition unit 100 is mounted at a position adjacent to a camera mounted for front sensing and collects information on the front lane detected through the camera.

The control unit 200 recognizes the lane of the driving vehicle through the lane information collected from the recognition unit 100 and compares the lane with the predicted traveling route.

The output unit 300 guides the information on the actual lane and the expected path lane of the driving vehicle compared through the control unit 200.

The output unit 300 preferably guides the user through video and audio when guiding the lane information, so that the driver can concentrate on driving without visually and visually worrying the driver.

Here, the control unit 200 is interlocked with the ECU (Electronic Control Unit), the output unit 300 is to be interlocked with the navigation mounted on the vehicle, the control unit 200 through the collected lane information of the driving vehicle It is preferable that the output unit 300 guides the information on the actual lane and the expected route lane of the vehicle being driven through the navigation while comparing the lane of the lane with the actual road.

Hereinafter, functions and effects of the present invention will be described.

As shown in FIG. 1, the recognition unit 100 for recognizing the lane of the vehicle, the control unit 200 for recognizing the lane of the vehicle and comparing it with the lane of the expected course, and the actual lane and prediction of the vehicle being driven The output unit 300 for guiding information on the route lane is provided to provide the driver with lane information on the vehicle being driven by comparing lane information of the actual road with lane information of the driving vehicle.

The lane recognition route guidance system of the present invention recognizes the lane of the vehicle being driven through the recognizer 100, and then is recognized through the recognizer 100 by the controller 200 interlocked with the ECU. The route information is generated and finally, the route information is guided by the output unit 300 interlocked with the navigation device mounted on the vehicle. When the intersection is entered, the route information is determined to provide a driving lane through the display. will be.

On the other hand, the present invention is to determine the need to change lanes by feeding back the lane information of the driving vehicle, when the driver is driving in the lane that fits the route so that the driver can continue to drive by taking no action, When driving in these other lanes, the driver can be guided through a display and voice, and a warning message can be provided when the vehicle is driving in a lane that is not available, such as a bus lane and a shoulder.

As such, when the lane recognition route guidance system is constructed in the vehicle, as shown in (a) to (c) of FIG. 2, the driver may be actively guided to the lane under various lane change conditions, and at the same time, FIG.
